# What is "signing a message" in when connecting wallet?

Signing a message is basically encrypting a string using your wallet. Like on-chain messaging.

This is typically used to check the ownership of a wallet in many websites / dapps.

However malcious developers or websites can request you to sign a string and this string can be something like sending ETH or swapping ETH to random tokens etc.

**Make sure to read what string they request to sign** and always avoid something like signing function style strings like swapExactETH(...) or Multicall() etc.

Our Dapp requests you to sign `insidor_dapp` string which is used to encrypt your private key of new accounts to store on your local storage.

Always make sure you make a backup of these accounts.
